摘要
EoC技术能够充分利用广电同轴接入网络资源,通过对现有网络的改造实现双向通信,承载以太网业务,实现数据、视频、语音等多种业务的融合,因而得到广泛关注,通过比较与分析,并结合我国有线网络资源的现状,给出EoC技术的合理选择。
Taking advantage of radio and television coaxial access network resources, through the transformation of the existing two - way communication network, EoC technology could carry Ethernet services ; make the integration of services such as data, video, voice and other business. So, EoC technology has been received wide attention. In this paper, through a series of comparison and analysis, combined with the status quo of China wired network resources, a reasonable choice about the EoC technology has been given.
